Example 1: sort javascript array
var points = [40, 100, 1, 5, 25, 10];
points.sort((a,b) => a-b)
Example 2: mdn js sort
var numbers = [4, 2, 5, 1, 3];
numbers.sort(function(a, b) {
return a - b;
});
console.log(numbers);
Example 3: javascript sort
var names = ["Peter", "Emma", "Jack", "Mia", "Eric"];
names.sort();
var objs = [
{name: "Peter", age: 35},
{name: "Emma", age: 21},
{name: "Jack", age: 53}
];
objs.sort(function(a, b) {
return a.age - b.age;
});
Example 4: how the sort function works javascript
const unsorted = ['d', 'd', 'h', 'r', 'v', 'z', 'f', 'c', 'g'];
const sorted = unsorted.sort();
console.log(sorted);
const unsortedNums = [45, 56, 3, 3, 4, 6, 7, 45, 1];
const sortedNums = unsortedNums.sort((a, b) => {
return a - b;
});
console.log(sortedNums);
Example 5: array sort js
arr = ['width', 'score', done', 'neither' ]
arr.sort()
arr.sort((a,b) => a.localeCompare(b))
arr = [21, 7, 5.6, 102, 79]
arr.sort((a, b) => a - b)
Example 6: sorting in js
var arr = [23, 34343, 1, 5, 90, 9]
var sortedArr = [];
arr.forEach(x => {
if (sortedArr.length == 0)
sortedArr.push(x)
else {
if (sortedArr[0] > x) sortedArr.unshift(x)
else if (sortedArr[sortedArr.length - 1] < x) sortedArr.push(x)
else sortedArr.splice(sortedArr.filter(y => y < x).length, 0, x)
}
})
console.log(sortedArr);
console.log(arr.sort((a,b)=>{
return a-b;
}));
